Reddit's CEO has put a name on a trend publishers have been feeling for a year. On October 29, 2026, the day Reddit reported third-quarter results, Steve Huffman told CNBC that search referral traffic from Google was "down meaningfully in this quarter" because of the "shift to AI mode and AI overviews." Revenue beat estimates. Users did not, and the company said it will test requiring everyone to log in.
This post sticks to what Reddit and CNBC reported, separates the CEO's attribution from the measured numbers, and explains what it means for anyone whose traffic depends on Google. It is a business story with a direct AI-search consequence, so the practical section comes first.
TL;DR: Reddit Q3 2026 in one table
| Item | What was reported |

What Huffman said
According to CNBC's report, Huffman told the network that Google search referrals "went down meaningfully" in the quarter because of the "shift to AI mode and AI overviews." He said previous Google algorithm changes would "kind of come and go," but the company's AI efforts represent "a fundamental shift in how the Google product works, from being a traffic driver to whatever's going on now."
He added that "that relationship between Google and the rest of the internet is evolving," and that for Reddit this means "a continued focus on our core users that come to Reddit directly." CNBC reports Huffman said search referral traffic is down meaningfully this quarter and that the trend will continue in the fourth quarter.
There is a history here. A Google update meant to surface "authentic" forum content helped Reddit grow its audience over the past few years, in CNBC's account. The AI features have since reversed some of that benefit, because an AI summary can answer the question without a click. Our earlier look at how Google's AI Mode ads and slowing search growth fit together gives the Google side of the same shift.
Claimed versus measured
The attribution is the CEO's, made to CNBC and repeated on the call. That matters for how to read it.
Measured by Reddit and reported by CNBC: the revenue, EPS, DAUq and ARPU figures above. US DAUq fell 2% year over year. Reddit's revenue growth slowed to 53%, which CNBC notes ended eight straight quarters above 60%.
Stated by Huffman, not independently measured: that Google's AI Mode and AI Overviews are the cause of the referral decline. It is a plausible and widely discussed explanation, and it comes from the person with Reddit's server logs, but Reddit does not publish a full referral series. The shareholder letter itself says search referral traffic was "down meaningfully in Q3, with the decline accelerating later in the quarter," and that the biggest impact was on logged-out and web traffic.
From Reddit's own shareholder letter: the company's Q3 2026 letter to shareholders (SEC exhibit 99.2) says the declines continued into early Q4, that "during October, we have seen that search traffic has dropped by more than 1 million referrals on average per week," and that if that rate continues, total DAUq "could fall in Q4, by a low-double-digit percentage from our current base of 130 million." That is a company projection, not a result. The letter attributes the shift to how search is evolving into "an AI-powered destination itself" rather than naming Google in that passage; the explicit Google AI Mode attribution is Huffman's to CNBC.
Stock reaction: CNBC said shares dropped over 15% after the numbers were released. We are not covering the share price beyond that; it is not the story.
The login requirement
Alongside the numbers, Reddit said it plans to require all users to create accounts, ending what Huffman called the last big platform with "basically unfettered logged-out access." He said: "Reddit is the last platform to provide basically unfettered logged-out access, and that's largely because of me, I've been holding that line."
Details from CNBC:
- Testing begins in the fourth quarter outside the US.
- No timeline for the full change; implementing it "would involve a lot of complexity."
- Reddit is still deciding what logged-out users will be able to see.
- Logged-in users are worth more: Reddit says they are more active and more valuable to advertisers, and Huffman said app users and logged-in users, both up quarter over quarter, drive most revenue.
We covered the earlier announcement of this strategy, including the scraping argument and the test-market plan, in Reddit goes primarily logged-in. The Q3 results add the numbers behind it: when the front door of search stops sending visitors, the logged-in direct audience is what is left to grow.
The licensing angle: Reddit sells data to the companies cutting its traffic
The awkward position is plain. Reddit's two biggest data-licensing partners, per CNBC, are OpenAI and Google. Google's AI features now answer questions partly from forum content like Reddit's, while sending fewer visitors. Reddit's "other revenue," which includes licensing, rose 35% to $48 million in the quarter.
Huffman said Reddit remains "in negotiations" with Google over its data-licensing agreement, and will "only do a deal that makes sense for Reddit." Earlier reporting suggested the original 2024 deal approaches its end; Reddit has not said what the outcome will be. Until a new deal is announced, there is nothing confirmed about its terms, and we are not guessing.
The same tension runs through the wider fight over AI training and content access. OpenAI said the same day it will honor a shared robots.txt signal for training preferences, which we cover in OpenAI's shared robots.txt signal. Signals and licensing deals are two ways content owners try to set terms; a login wall is a third.
Why this matters if you publish or build on search traffic

Reddit is an unusually clean test case, because Google had favored it for years. If AI answers reduce clicks to a site that Google actively promoted, smaller publishers have little reason to assume they are exempt. Our earlier piece on Google Zero and publishers threatening to block crawlers tracked claims of 40% traffic drops; Reddit's report is another data point, not proof of a universal rate.
Practical steps:
- Measure your own referrals. Compare Google organic clicks quarter over quarter in Search Console, separating queries where AI Overviews appear when you can. Do not borrow Reddit's story as your diagnosis.
- Invest in direct channels. Newsletters, apps and accounts convert occasional visitors into a repeat audience. Reddit's own response is to grow app and logged-in users.
- Write for citation as well as clicks. Being the source an AI answer cites is a different goal from ranking. Our explainer on generative engine optimization covers what that looks like.
- Decide your crawler policy deliberately. Blocking AI crawlers reduces some uses of your content but also visibility. Make the choice per section rather than site-wide by reflex; our guide to protecting a small site from AI bot floods shows the operational side.
- Do not wall off a site until you know the cost. Reddit can require logins because it has a huge direct audience and apps. A small site that does the same may simply disappear from view.
What to watch next
- Q4 guidance. Reddit guided to $1.0 to $1.03 billion. The next report will show whether direct and app growth offsets weaker referrals.
- The Google deal. A renewal, a new structure or a lapse would be the clearest evidence of how Google values forum data now.
- Login tests. Which markets, what logged-out users can see, and how usage moves.
- Google's response. Google has not, in the sources we reviewed, commented on Huffman's attribution. If it publishes referral data or changes AI Mode's linking, that would change the picture.
- Other platforms. Whether other large forums and publishers report similar declines on their calls.
Bottom line
The verified part is simple: Reddit beat Q3 estimates, guided below Wall Street for Q4, lost US users year over year, and said it will test mandatory accounts. The notable part is the CEO's attribution to Google's AI features, which is a first-hand claim from a company that sells its data to Google and depends on its traffic. It is credible, consequential and not yet independently quantified. If you depend on search, treat it as a prompt to measure, not a reason to panic.
